As a consequence, there is low agreement on the sign of the net change in global mean temperature as a result of land use change. (climateaudit.org)
The strength of the radiative heat loss to space per unit warming of global mean surface temperature is a key quantity of interest, as usual. (gfdl.noaa.gov)
This is related to determining the uncertainty in an estimate of global mean sea surface temperature, or of a trend over multiple years. (skepticalscience.com)
